The later is very easily reproduced by killing zebra. This is a rather serious problem because it makes FreeBSD unusable as a VLAN router in a data center. I filed a PR for this including the traceback (kern/54314), but on examination of the gnats database I found that this problem was also reported in (kern/40723) with a more accurate problem description than mine. I would like to resolve this issue but I do not know how to proceed: can someone help me with this and do they need more info to do so? Or is there are detailed description of this part of the kernel available, so I can look for the bug myself? Thanks for any advice. Frank
